It will stay. No need to delete it, but I think you need to seriously rethink your understanding of the Buddha's teachings.
There is no two infinity possible, where one infinity will limite another infinity by his simple presence, there is could not be one infinity for Hinduism, one another from Muslims etc. So any who speaks about eternity speak about the same. They speaks about infinity. There is one muslims proverb : If somethink what you want to say is less important that silence, so shut-up. Silence is pure, non-created, unconditioned, the nature of all noize. Also it's said that after the enlightement of Gotama, Budhha have never said anythink (of corse it's an internal point of view)
Only that have been never created that can be eternal. So any who speaks about nothink, about purity, about non-created, about beyond thinking, beyond fenomena, nature of fenomenas, unconditioned so they speaks about the same.
So Yes, all religions speaks about the same, by different way. Ajhan Buddadasa, Ajhan Sumedho etc are agree with it. Interpretation is different - yes, way that Dhamma is explained is different - yes, but the Dhamma it self (law) is the same.
If it brings freedom? Yes. Because it's unconditioned, free, pure from all, have no any substance, no space, no time, free from all, like a lotus. That why i said "nothink".
If it's the nature of all fenomenas? Yes. Because it's purity is the condition of all existance. Like a silence is condition to noize, like a canvas is condition to picture, like a stability is condition to mouvement, like a ground is condition to building. Thats why i said "Buddha Nature"
If it's anatta? Yes. Because it's not created. Thats why i'am sure that it's not Hindu conditioned interpretation like a eternal self, or Brahma.
Perharps explanation is imperfect, perharps it can not be explained, perharps the way of explanation is not the same, but it's Nibbana.
If i could re-ask you, because you dont answer, what hear your internal voice?
